Post subject:  limit to the number of font colours available?

I'm trying to set the colour of a paragraph to a specific colour, but the produced PDF is a lot darker.

In the attachment the "ran" is the darker colour being produced and the "Are Ba" is the colour I want.
I have tired:
Code:
//style.Font.Color = Color.FromCmyk(1,0,0.545,0.310);// - is white / transparent
//style.Font.Color = Color.Parse("0x00B050");//too dark
style.Font.Color = new Color(0, 176, 80);//too dark

and both produce the same darker colour.

Is there a limit to the colors that can be used?

Hi!
You specify "(0, 176, 80)", PDFsharp writes "(0, 176, 80)" into the PDF file. Color profiles may be accountable for the visual difference, but that is not my area of experience.

BTW: Try Color.FromCmyk(100,0,54.5,31) instead (value range 0 through 100).

BTW2: Are you creating a CMYK PDF file? I tried the color "(0, 176, 80)" in an RGB PDF and I got the bright green (left part of image).

fantastic, I had

document.UseCmykColor = true

right at the top of my code.

Removed it and all is good with the world again
